Marine Heatwaves Hotspots within Philippine Economic Exclusive Zone (PEEZ)

This repository hosts maps depicting the hotspots of various metrics of marine heatwaves within the Philippine Economic Exclusive Zone (PEEZ).

Description

Metrics	Description	Image Filename
Duration	Total days or period of a MHW occurrence	duration.png
Frequency	Number of MHW events in a year	frequency.png
Cumulative Intensity	Sum of the daily anomalies during an MHW	icum.png
Maximum Intensity	Maximum temperature anomaly during an MHW	imax.png
Mean Intensity	Mean temperature anomaly during an MHW	imean.png

Limitations

The analysis is based on the sea surface temperature anomalies that are more than the 90th percentile of the mean climatology from January 1, 1982 to December 31, 2011. Values were re-gridded through spline interpolation.

Data Source

This analysis used the daily Global Ocean OSTIA Sea Surface Temperature and Sea Ice Reprocessed dataset from the Copernicus Marine Service covering the period January 1, 1982 to December 31, 2021 with 0.05 deg x 0.05 deg spatial resolution.
